You may wish to look at the number of scientists who do not buy into global warming. With arctic ice coverage expanding and global temperatures holding steady or dropping despite continuing increase in CO2, the case for catastrophic global warming appears weak.

If you look at climate history, you will find that change is ongoing; sometimes slow and sometimes amazingly fast. The earth at times has been a great snowball where everything was covered in ice and at other times has had zero surface ice. The simple answer is that we do not have any proven data or algorithm on which to base a prediction.

Moving away from the use of imported oil will reduce our CO2 emissions. This is something that both the GW alarmists and skeptics can support. (with the exception of Al Gore, of course) Putting in a cap and trade system will be a disaster for American industry. It will require that we have nations that do not have a program of reducing CO2 take over all energy intensive energies including steel, aluminum, copper, etc. I'm sure the Chinese will be grateful.
